An interferometric approach to SAR imagery of scenes with motion
Abstract
This paper develops an interferometric approach to the problem of imagery of a scene in which scatterers' motion would cause their erroneous displacement in azimuth in a conventional single synthetic aperture image. Treating the important case where radial motion predominates, the technique can be cast into a problem in beam steering in velocity space to obtain the scatterer motion estimates. In this way a super-resolution is achieved, i.e., one which can distinguish scatterers within a conventional SAR cell on the basis of radial velocity differences. Noise and clutter effects are explicitly treated.
